Lauren Weisberger

Returning to the United States after her backpacking expedition, Weisberger settled in Manhattan, where she was hired as assistant to Vogue editor Anna Wintour. After ten months, she and Vogue features editor Richard Story left the magazine. Weisberger said she felt out of place at the magazine, though Vogue managing editor Laurie Jones later said, "She seemed to be a perfectly happy, lovely woman".[5]

Weisberger and Story began working for Departures, an American Express publication, where she wrote 100-word reviews and became an assistant editor. She also published a 2004 article in Playboy magazine.[6]

After mentioning her interest in writing classes to Story, he referred her to his friend Charles Salzberg. She started writing a story about her time at Vogue, and completed it by trying to write 15 pages every couple of weeks. After repeated urgings, she showed the finished work to agents; it sold within two weeks.

Weisberger's first book, The Devil Wears Prada, was published by Broadway Books in 2003; it spent six months on The New York Times Best Seller List. By July 2006, The Devil Wears Prada was the best-selling mass-market softcover book in the nation, according to Publishers Weekly.

The Devil Wears Prada is a semi-fictional but highly critical view of the Manhattan elite, largely based on Weisberger's experience at Vogue magazine. There is much speculation that book's primary character Miranda Priestly represents Wintour and the fictional Elias-Clark publishing company in the book is modeled after Condé Nast. The book focuses on many comical aspects of a first job in the world of elite fashion.

While commercially successful, the book was not well received at Vogue. Kate Betts, a Vogue editor, criticized Weisberger and the book in The New York Times, writing that Weisberger and Wintour are actually the direct counterparts of their fictional characters and that "Andrea is just as much a snob as the snobs she is thrown in with."[7][8]

Film rights to The Devil Wears Prada were acquired by 20th Century Fox, which released a movie of the same name in June 2006, starring Meryl Streep (as Miranda Priestly) and Anne Hathaway (as Andrea Sachs).[9] The film grossed $27.5 million in its opening weekend,[10] and amassed U.S. sales of nearly $125 million and worldwide sales of $326 million,[11] making it one of the top-grossing films of summer 2006.

The film departs from the book in several ways. For example, in the film, Andrea is a graduate of Northwestern University; in the book, she is a graduate of Brown University. The film depicts Miranda asking Andrea to accompany her to Paris when a colleague falls ill. The book, however, has Emily catching mono and being unable to go with Miranda. In the book, Andrea's best friend Lily is an alcoholic who gets into a car crash, leaving Andrea to decide whether to stay with Miranda in Paris or return to assist her friend. The movie does not include any of these details and ends with Andrea and Miranda parting in Paris but viewing each other with mutual respect. In the book, however, Andrea curses Miranda to her face and is consequently fired.

Weisberger made a brief cameo in the film as the twins' nanny.

In October 2006, Fox acquired the television rights to the book, though the series was ultimately never developed.[12]

Weisberger secured a $1 million advance from Simon & Schuster for her second novel, Everyone Worth Knowing, which based on the trials and tribulations of the New York City public relations world; the book was published in fall 2005. It received generally unfavorable reviews. The New York Times Book Review described it as "fatuous, clunky." USA Today called it "lackluster imitation" and Entertainment Weekly said it was a "ho-hum rehash" of The Devil Wears Prada.[13] It debuted on The New York Times Best Sellers List at No. 10, but dropped off the list in two weeks and was ultimately noted for disappointing sales.[13] The audio book was read by actress Eliza Dushku. In some European countries, the novel was released under the separate title Gossip and Gucci.

Chasing Harry Winston, Weisberger's third novel, was released May 27, 2008 and on May 19, 2008 in the United Kingdom. The book's main characters are three best friends in New York City, Emmy, Adriana, and Leigh, who are facing fears with turning 30. Recently dumped Emmy promises to make a drastic change and find guys from every continent for casual affairs. Beautiful Brazilian Adriana tries to leave her old lifestyle of sleeping around and living off her father to get a Harry Winston ring on her finger before her first wrinkles begin showing. Leigh, the one with the perfect life, does not know what she needs in order to be happy and relax.

In September 2008, Universal Pictures secured rights to the book, and it was translated into French, Dutch, and Italian. In some European countries, the novel was released under the separate title Chanel Chic. In Italy, the title is Un anello da Tiffany & Co (A ring from Tiffany & Co). In France, the title is Sexe, diamants et plus si affinités (Sex, Diamonds, and maybe more...)

The book was panned by critics and was voted "#1 Worst Book of 2008" by Entertainment Weekly.[14]

Last Night at Chateau Marmont was released in August 2010.[15] It debuted at No. 9 on the New York Times Bestseller List on September 5, 2010.[16]

Revenge Wears Prada, a sequel to The Devil Wears Prada, was released on June 4, 2013. It debuted at No. 3 on The New York Times Bestseller List.

The Singles Game was released in 2016.

When Life Gives You Lululemons, a second sequel to The Devil Wears Prada, was released in 2018. It follows the character of Emily Charlton, Miranda's Priestly's assistant played by Emily Blunt in the movie adaptation. This book has also been published under the title The Wives.

Where the Grass Is Green and the Girls Are Pretty was released in May 2021. This book has also been published as a paperback in the United Kingdom and Ireland under the title One Little Lie.

Her short story "The Bamboo Confessions" is included in the anthology American Girls About Town. It is about a New York City backpacker who travels around the world and, in so doing, begins to view her love life back home in a different light.[17]
